added support for one way replication

added revision support to the delete function

fixed sql error

cleaned up code

removed package doctype filtering from the resultset.

changed accession number schema to <sitecode>.<serialnumber>.<revisionnumber>. DocumentIdentifier.java parses docids into parts for easy manipulation.

Modified stylesheets and server code to use a single "read" action instead

process, developed and started to utilize a new suite of URL "protocol
handlers" that are in the package "edu.ucsb.nceas.protocols" and handle...

Added a new URL protocol handler class for the metacat protocol. This
class will replace the current MetacatURL class in a much simpler and
extensible manner. See the documentation for java.net.URLConnection and
java.net.URL for details.

this class allows the parsing of xml data sent by a replication server to assertain document info about a remote document.

added functionality to allow the replication servlet to assertain and insert user and group info into the local database. started implementation of insert replication handler (it is commented out in this commit)

fixed compatibility problem by overloading the write method. Jivka's new parameter (Reader acl) is now defaulted to null if it is not explicitly declared.

Fixed problem with AuthInterface, AuthLdap, and AuthMcat where the
sigantures of the methods of these classes were not in agreement, which was
causing AuthLdap to no longer compile. Changed parameter signatures so that
the 'user' parameter is used consistently in all of the methods.

Began work on new UI for the KNB web site. It will be the main query
interface from the KNB website.

Fixed the LDAP authentication adapter (AuthLdap.java) so that it now looks up

DBSAXHandler and uses new(separate) db connection....
